Airsoft Pistol Product Details

Green Gas TSD Caspian 45-Tactical Pistol Tan FPS-400 Full Metal, Blowback, Rubberized Grip Airsoft Gun

Airsoft Pistol Product Features

This is a Green Gas Airsoft Pistol which means that it uses Green Gas as a propellant. It shoots hard and fast and is extremely lifelike. One feature many Green Gas Airsoft Guns have is blowback, meaning that as the BB is propelled forward the slide thrusts backward mimicking the kick of a real gun! This Green Gas Airsoft Pistol doesn’t require any pumping just simply point and shoot. This is a high end Green Gas Airsoft gun. Please only use .20 gram high quality BBs with this item in order to keep it in working order. Using anything else as ammunition for this gun will void the warranty and may cause it to jam. You must be 18 years of age or older to purchase this Airsoft gun. You will need to purchase Green Gas for this gun separately.

Airsoft Pistol Design Information

Find information about airsoft pistols and handguns and how you can use them as extra guns or as primary weapons on the airsoft playing field. Many airsoft pistols are fully manufactured and licensed replications of their actual handgun equivalents and run and look in the same ways while shooting airsoft BBs rather than actual bullets.

There are a variety of airsoft pistols such as CO2, propane or green gas (blowback and non-blowback), spring powered, and AEG automatic electric handguns. Each of these types of handguns have positives and negatives associated with them. Finding out about the styles of airsoft handguns helps you choose which type is right for you and your airsoft gameplay style.

CO2 Airsoft Sidearm Details

CO2 airsoft pistols are one of the most tough and common types of sidearms. These handguns use CO2 stored in small cylinders to push airsoft BBs out of the weapon barrel.

These styles of airsoft pistols are good for playing airsoft in colder weather conditions due to the fact that the pressurized CO2 gas is stored in the sealed cylinders and less prone to performance variations by temperature levels. This provides great FPS and shot consistency while playing airsoft in the winter season for instance where other types of pistols like green gas stuffer from low performance or hardly shoot BBs.

About CO2 Gas and CO2 Cartridge Cylinders

CO2 airsoft pistols are powered by standard 12 gram CO2 cartridges. These cartridges look like a shiny steel cylinder and contain high-pressure CO2 gas consisting of a single carbon atom and two oxygen atoms, therefore the molecular formula of “C + O2 “. These atoms are connected in the following alignment “O= C =O”. The gas is held in the 12 gram cartridge cylinders under extremely high pressure of around ~ 800psi which correlates to 55bar.

The CO2 cartridges are not multiple-use and you can usually purchase them in bundles of 12, 20, 50, or 100 12 gram CO2 cartridge sets. They come sealed to keep the CO2 gas safely and securely inside, but soon after they are punctured (firing them in an airsoft handgun breaks the cartridge seal) cartridges will begin to lose pressure if they are left unused. You need to attempt to consume the entire CO2 cartridge the very same day you open the seal. If the airsoft matches end and you still have CO2 gas left, use the chance to do some pistol target practice and use up the rest of the excess gas. There is no gas level gauge on the cartridge so you have to shoot up until the weapon stops firing.

CO2 cartridges can be stored for a while if the cylinders are stored sealed. They have the manufacturer’s expiry date usually listed on the package or cylinder, however they will probably survive for a prolonged period past this date if the cartridge seals are not broken.

Green Gas Airsoft Handgun Details

Green gas airsoft pistols are similar to CO2 handguns, however they use green gas instead of CO2 cartridges. The operational impact on the battlefield and green gas weapon efficiency is almost the very same as CO2 pistols with the guns at around 300+ FPS.

The green gas is stored in the handgun’s grip within the magazine which can frequently hold in-between 15 to 20+ 6mm BBs depending upon the handgun model. A series of valves, rubberized gaskets, and o-rings keep the propane gas sealed in the mag until the pistol’s trigger is squeezed. It is a great choice to refill and top off the propane supply in the magazine each time you reload it. Pistol-wielding gamers can additionally carry excess bottles of green gas or propane in the field for reloading mags in-between breaks in the war or in-between activities.

When using a green gas pistol on the airsoft field or arena as a primary or secondary gun, bringing additional mags is suggested for rapidly reloading and getting back into the game. Having extra mags on-hand helps you get back in the action in the middle of firefights or while clearing buildings in CQB (close quarters combat) room-to-room fighting.

Green gas handguns are ideal for CQB at airsoft fields given that rifles and full-sized AEGs are normally not permitted to be used for indoor shooting. This is an essential safety standard because of the close range proximity of players during the shooting engagements. While green gas pistols can still fire airsoft BBs at around 300 FPS, the short pistol barrel assists to keep the joules and energy forcing the BB at a lower level compared to AEGs, airsoft rifles, sniper rifles, and other long guns.

About Green Gas Blowback (GBB) VS Green Gas Non-blowback

There are two different varieties of green gas airsoft pistols. First there are green gas blowback pistols or GBBs. These handguns run like an authentic handgun with the gun’s slide “blowing back” and cycling with every shot. Each time a new airsoft BB is loaded into the chamber, the gas triggers the slide to cycle. The result is extremely cool, but the GBB guns usually are more expensive and possibly have more which can break. The green gas non-blowback airsoft pistols have a stationary slide which does not cycle. The non-blowback guns commonly cost less than GBBs. Efficiency is about the same between the two kinds of green gas pistols.

About GBB and Green Gas Issues

Since the green gas or propane gas is housed in the magazine by using rubber o-rings, seals, and silicone gaskets, cold temps can negatively impact these gaskets and allow the gas to leak out before shooting the gun. This lack of pressure can cause the airsoft BBs to merely shoot a couple of feet (like 10 feet in cold weather ) when it would usually shoot 6mm BBs over 100+ feet in warmer temps).

One solution to this problem is to make the GBB pistol magazines warmer by holding them next to your body just before game play starts. If you truly need to play with a trustworthy airsoft pistol in the cold weather, it may also be worth getting a CO2 style of your favorite handgun.

Spring Airsoft Sidearm Info

Spring airsoft guns are powered by strong springs with irregular pitches that launch the airsoft BBs down the handgun barrel. They are generally single shot. The manual actions of firing, cocking, and reloading spring airsoft guns makes the weapon’s fire rate much slower than CO2 and GBB handguns. When facing airsoft players on the airsoft field with upgraded weapons, auto airsoft AEG SMGs, sniper rifles, and CO2 or GBB airsoft pistols, this makes spring guns entertaining to use, but less efficient.

Spring handguns work best in springer wars where participants can just use related, single shot spring weapons or as a close quarters weapon for CQB buildings and MOUT sites when you can frequently quietly sneak up on other airsoft opponents to get an assured one-shot-one-kill. In the latter circumstance, a rapid second follow-up shot is not needed considering that the other person is now hit by the airsoft BB and out of the gameplay or running back to respawn. Be careful when engaging a number of airsoft players considering the gun just fires as quick as you can re-chamber an airsoft BB by hand.

About Spring Pistol Effectiveness

Spring guns are incredibly useful under the right scenarios and airsoft games. Their FPS normally chronos at around 250 FPS to 300 FPS with lighter weight 0.12 gram airsoft BBs. These weapons generally fire the lighter weight airsoft BBs due to the fact that the pitched springs are less powerful than other styles of airsoft guns like rifles. Spring handguns can usually be accurate at up to 120 feet or more with 0.12 gram BBs however accuracy decreases quickly. Using normal 0.20 gram weight airsoft BBs, you will very likely have a decreased range of around 60 to 80 feet or less with increased target accuracy.

AEG Automatic Electric Airsoft Pistol Info

AEG airsoft sidearms or AEPs (automatic electric pistols) are also an option to carry as a backup gun on the airsoft field. These automatic electric handguns are normally powered by mini stick batteries in the pistol’s butt. They function similar to an AEG SMG and use compressed air with electrically cycled cylinders, pistons, and gearboxes to shoot airsoft BBs quickly and rapidly.

AEG pistol magazines usually hold around 20 to 30 airsoft BBs. The pistols can shoot airsoft BBs as high as around 300 FPS when loaded with 0.12g airsoft BBs or about 200 to 250 FPS using 0.20 gram airsoft BBs. The electrically powered gearbox system can shoot around 700+ BBs per minute which depends on if you have enough spare mags to reload and the battery lasts that long. These handguns can efficiently shoot airsoft BBs at around 150 foot ranges.

AEG Handgun Quality and Efficiency

AEG handgun quality has actually increased significantly recently. The first generation AEP guns were a little bit unreliable and questionable, but the newer versions have the deficiencies resolved and make reliable airsoft secondary weapons. They can be upgraded with increased magazine capacities and also accommodating larger batteries.

A significant perk of carrying an AEG pistol is that you have the capacity to rewire the adapters to use an enhanced capacity battery with longer life. Based on the AEG pistol model, you can gain a substantial boost in performance by using a two cell Lipo battery (2S Lipo) rather than the stock AEP battery. Take care of tweaking the elements and wires because you need to consider the volts, mAh, and loads of the battery. If you have modding concerns, ask a pro gun tech at your closest airsoft store.

Which Airsoft Handgun is Best for Me to Buy?

If you have $100 or more to spend on your airsoft pistol, check out a GBB pistol or automatic electric pistol. If you have between $50 to $100 to invest, check out a CO2 pistol or cheaper GBB pistol. You can still play with a durable airsoft handgun by checking out cheaper pistols and by trading with other players in the used airsoft gun market if you are on a budget.
